WebPaper Abstract. Wafers at FBEOL layers traditionally have higher stress and larger alignment signal variability. ASML’s ATHENA sensor based scanners, commonly used to expose FBEOL layers, have large spot size (~700um). Hence ATHENA captures the signal from larger area compared to the alignment marks which are typically ~40um wide.
